SHUTTLE-BINDER FOR LOONIS.

SFECIFICATION forming part of Letters Patent No. 408,470, dated August6, 1889.

Application iilecl 22, 1889. Serial No. 311,677. (No model.)

To all whom t may concern:

Be it known that I, ELLIS EARNSHAW, a citizen of the United States, anda resident of Grafton, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvementl in,Shuttle-Binders for Looms, of which the following is a specification,vreference being had to the accompanying drawings, representing suchportions of a loom as embody my inventiomandin which- Figure Irepresents a t-op view of one end of the lay, showing the shuttle-box.Fig. 2 is a front view of the same, and Fig. 3 is a sectional view of aportion of the shuttle-binder and stud upon which the binder is hinged.

Similar letters refer to similar parts in the different figures.

My invention relates to t-he lay of a loom; and it has for its object tosecure a uniform and regular action of the shuttle, and also to causethe protector-iinger to be moved uniformly by the motion of the binder;and my invention consists in the improvedmanner of hinging the binder tothe lay, as fully described hereinafter, and specifically setforth inthe subjoined claims.

In the accompanying drawings, A denotes a portion of the lay; B, theshuttle-box; C, the binder, hinged at one end to the lay. D denotes thebinder-spring. E is the protectorfinger, attached to a protector-rod F,and having its free end resting against the free end of the binder O. Atorsional spring G is applied to the rod F to hold the finger E againstthe binder O.

The construction and operation of the parts above described are commonto weavinglooms, and will therefore be well understood without detaileddescription.

As the shuttle :is driven into the shuttlebox by the picking mechanismof the loom, it is brought into contact with the inner convex side ofthe binder, carrying the free end of the binder outward, moving thefinger E, and slightly rocking the rod F in the usual and Well-knownmanner. The frictional contact of the binder upon the shuttle holds theshuttle from any rebound as it enters the box, and it is important thatthis frictional adhesion should be regular and uniform in order that auniform resistance shall be offered to the force of the picking'mechanism. It is also necessary that the swinging motion of the binderupon its pivotal stud be uniform in order to secure the uniform rockingmotion of the protector-rod by means of the protector-finger E. Thepressure of the binder-spring D is applied near the central section ofthe binder at a, and as the inner end l] of the binder is held bytheforce of the spring applied to the protector-rod the action of theshuttle as it is thrown into the box will tend to carry the hinged endof the binder outward, and any lost motion caused by the wear of thebinder upon the pivotal stud will be constantly increased by theoperation of the loom, causing the hinged end of the binder to yield,thereby reducing the motion of the end l) of the binder and decreasingthe rocking motion of the rod F. The yielding of the hinged end of thebinder will also vary the pressure of the binderspring upon the shuttle,and consequently vary the resistance of the shuttle to the pickingmechanism of the loom.

Y The inner side of the binder should present a true vertical wall tothe Contact of the shuttle, and in case the binder or its pivotal studbecomes irregularly worn the binder is often allowed to tip and bearagainst the corner of the shuttle.

To secure the regular and uniform action of the binder is the object ofmy present invention, and this obj ectI accomplish by means of themechanism shown in the drawings and hereinafter described.

In place of the ordinary stud now in common use, upon which the binderis hinged and which passes through a hole in the outer end of thebinder, I employ a hollow stud II, provided with a iiange I and attachedto the lay by means of a nut J upon the screwthreade'd section K of thestud, in the usual manner in which the binder-studs are now attached tothe lay. The stud IfI is provided with the longitudinal concentricchamber L. The end c of the binder is bored to receive the hollow studII, forming a chamber M, which extends partly through the binder, and inthe end wall N of the chamber M, I place IOO the pin O, rigidly attachedto the binder and concentric with ,the chamber M, the pin O fitting theconcentric chamber L in the stud II. I thereby secure a doublebearing-surface of the binder upon the outside of the stud II and of thepin O in the concentric chamber L. rlhe bottom ot the chamber Lalsoserves to contain oil or lubricating material, which is kept from beingthrown by the swing of the lay upon the woven fabric or upon the shuttleby means of the end of the binder, which forms a cap over the end of thehollow stud H. A thorough lubrication of the bearing is thus secured,which would not be possible with a bearing open at the top, as thecentrifugal force at cach swing of the lay would cause the lubricatingmaterial to be thrown out of the bearing. It will usually be foundsufficient to lubricate the binder-bearing only at the insertion of anew warp, when the binder can be readily lifted from the hollow stud Hby removing7 the free end of the binderspring C from oft the binder.

The piu O is provided with a shoulder d, which rests upon the end e ofthe stud 1I, forming a bearing to receive the downward pressure of thebinder C, rendering it more durable, as the pin and stud can be made ofsteel.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The combination, with/the lay of a loom, of a stud attached to saidlay and forming a pivot upon which the binder is hinged, said stud beingprovided with an interior chamber to contain lubricating material, and abinder ber and concentric therewith and fitting thev chamber in thestud, substantially as described.

3. The combination, with the lay of aloom, of a stud attached to saidlay and provided with a longitudinal concentric chamber open at theupper end of the stud, abinder hinged upon said stud, a pin 4held insaid binder fit ting the chamber in said stud and provided with ashoulder resting upon The upper end of the stud, substantially asdescribed.

4. The combination, with the lay of a loom, of stud H, having a chamberL, binder C, pin O, held in said binder and fitting the chamber L, andhaving shoulder (Z resting upon the end e of the stud H, said binderhaving a chamber M tting the stud H, substantially as described.
